Review of the Derale Series 8000 Transmission Cooler


Speaker 1: Today we'll be having a look at the Derale 8000 Series line of plate-fin transmission coolers. Here's what our transmission cooler looks like installed. Now, the reason you're gonna want an auxiliary transmission cooler such as this one on your vehicle is quite simple. Heat is the enemy of transmissions. It is the number one cause of premature failure on your transmission. By reducing the temperature of the fluid inside your transmission, you will extend the life of it, and also have added cooling abilities.

The colder the transmission fluid is, the more heat it can actually absorb. Plus, we are expanding the cooling capacity of the system by having additional room for more fluid, which, will also help reduce the temperature.Now, you may ask, "How is this important to me because my vehicle already has a transmission cooler build inside the radiator" Well, it's quite simple. If you we're ever planning on doing aggressive driving, or towing a trailer, towing a trailer causes additional wear and tear on your transmission, and causes increased fluid temperature. By cooling the temperature down further, you are making it easier on your vehicle in order to tow that extra weight. Now, how this works being installing in addition to the factory cooler inside the radiator, the fluid will leave the factory transmission cooler from the radiator, go inside of our auxiliary cooler here that we installed, get cooled down even further, and then go back into the return line that goes into your transmission.

So, you're adding additional cooling capacity, and a secondary cooler by having this aftermarket cooler installed.Now, for a few measurements to better assist you in choosing if this cooler's gonna work for your vehicle. At its widest point, it's 11" wide. From the very top to the very bottom, it's 7 1/4" tall, and it is 7/8 of an inch thick. Now, one thing our customers have noticed, when they're installing this cooler on a vehicle, they have noticed when they're installing it inline with the factory transmission cooler, that they have needed additional hose. Now, we do have additional hose available on our website.

Now, the 8000 Series of Derale transmission coolers are plate-fin design, and the plate-fin design increase surface area. The more surface area that we have, the more cooling capacity that we have. The more of your fluid you can spread out over a larger distance, the more it can get cooled down to reduce the temperature of your transmission.This cooler also features turbulator technology to help agitate the fluid passing through it. To help with heat transfer, but also to help prevent any drop in fluid pressure. Our transmission operates off fluid pressure, so if it falls below a certain amount, it may not shift gears properly.

By maintaining our fluid pressure, our transmission will shift gears properly, and work as it's designed. This cooler has an aluminum construction, so we don't need to worry about it corroding or rusting out over the course of time. It also has a nice gloss black finish, so it'll be easily concealed behind the grill of your vehicle, and it won't be visible are you're looking at the front of your car.And that completes our look at the Derale 8000 Series line of plate-fin transmission coolers.

If I wanted to eliminate the trans fluid from entering the radiator, would I need a bigger aux trans cooler? Also, is there a fluid temp sending unit/gauge available? Thanks 57168

These transmission coolers are intended to be a supplemental cooler in addition to the OEM transmission cooler system. If you are looking to replace your existing OEM cooler you will need to utilize the largest cooler that will fit in the space you have available. There is a temperature gauge available as part # D13009, and I have linked that for your reference. 50811

Do you have to add any transmission fluid 57474

Yes, since the capacity of the system is increased additional fluid would be needed once the installation is complete. You will just need to check it once everything is installed and fill it to the factory fill line on the dip stick. 50483
